+### First use logic
+
+Any use of the `short`, `long`, or `both` modifier will not count against the
+term's first use.
+
+This is useful, for example, when you want to use a term in a heading or a
+caption. In that case, your term might end up in an `outline()` at the top of
+your document. Normally you don't want that to count as a term's first real use.
+Normally you want that to happen in the body of your document. So, by using
+these modifiers in such situations, you can not only specify exactly how you
+want your term to appear, but also control whether it counts as a "first use".
